SPECIFICATION forming part of Letters Patent No. 710,785, dated October '7, 1902.

Application filed August 20, 1900, Serial No. 27,494. (No model.)

To all whom it may concern.-

Be it known that I, CHESTER A. LATnAM, a citizen of the United States of America, residing at Nichita, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Antifrietion- Bearings, of which the following is a specification, reference being had therein to the accompanying drawings and'the figures of reference thereon, forming a part of this specification, in which Figure 1 is a side view of the ridged journal and ridged rollers and a sectional view of the ridged boxing of my improvedantifrie tion-bearing. Fig. 2 is a longitudinal view of said rigid boxing. Fig. 3 is an end view of the bearing-collar removed.

This invention relates to certain improvements in antifriction-bearings; and it consists of a roller placed between a journal and boxing, said rollers, journal, and boxing having one or more spiral ridges surrounding them in an opposite direction from each end toward the center; and the object of my invention is toprovide an antifriction-bearing.

Referring to the drawings, at represents a journal. 5 representsa spiral ridge surround ing said journal in one direction from the outer'end of the bearing toward the center. 6 represents a spiral ridge surrounding said journal from another direction toward the center.

7 represents rollers, which are provided with one or or more spiral ribs or ridges 8,and said ridges wind around said rollers in an opposite direction from each end toward the center and are placed between said journal and boxing, as'shown in Figs. 1 and 3, said rollers being adapted to roll around said journal freely between said journal and boxing,

with the ridges 2, 5, and 8' each touching at its respective points of contact each time they surround their respective journal, boxing,

and rollers.

9 represents the collar at the end of the bearing.

Having thus described my invention, what I claim as new and usefuhand desire to secure by Letters Patent, is as follows:

1. The herein-described bearing comprising a journal provided with spiral ridges surrounding said journal, in opposite directions from each end toward the center, a boxing, the inner surface of which is provided with spiral ridges surrounding said boxing, in an opposite direction from each end toward the center, and aseries of rollers surrounding said journal,between the journal and boxing, said rollers having spiral ridges surrounding them from each end toward the center of each roller and the surface of said roller-ridges adapted to roll on the surface of the ridges of the boxing and journal, substantially as shown and described.

2. An antifriction-bearing comprising a journal having spiral ridges surrounding said journal, in an opposite direction from each end toward the center of said journal-bearing, and a boxing, having its inner surface composed of spiral ridges surrounding said boxing in opposite directions from each end toward the center, and a series of rollers adapted to rotate freely on said ridges of the boxing and journal, between the boxing and journal, substantially as shown and described.
